SPECIFICATION forming part of Letters Patent No. 592,286, dated o ctober26, 1897;

To 00% whom it may conccrn: 7

Be it known that I, JAMES W. GRANDLE, a citizen of the United States,residing near Marion, in the county of Linn and State of Iowa, haveinvented certain new and useful Improvements in Hand Nailing Implements;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to apparatus for feeding and driving nails, thedevice being more particularly adapted for shinglin g and the likeoperations where a portable hand instrument is required.

The invention consists in the construction, combination, and arrangementof parts, as hereinafter fully set forth and claimed.

In the accompanying drawings, forming a part of this specification,Figure 1, Sheet 1, is a side elevation of a nailer embodying myinvention. Fig. 2 is a view from the opposite side. Fig. 3 is asectional view in the plane of the line 00 :0. Fig. 4, Sheet 2, is aplan View with the lid of the nail-hopper removed and the plunger andtube in section. Fig. 5 is a sectional view of the hopper in the planeof the line 3 y. Fig. 6 is an external view of the hopper inperspective, showing the nail-delivery apparatus. Fig. 7 is aperspectiveview of the nail-feed slide as seen from the inner side.

Similar letters of reference indicate corresponding parts.

The nails are contained in a hopper A, attached to a tubular stock 13 insome suitable manner, as by clips at a. The hopper is closed by asuitable lid A. V In practicethis hopper is made with two plane verticalsides, and in the angle where they meet is mounted a slide 0, adapted tomove from the bottom to near the top of the hopper in a guide A. Nearthe upper edge of the hopper on the plane side adjacent the wider faceof the feed-slide C is an offset with an inclined ledge at the bottomthereof. This is provided with a longitudinal slot D slightlywider thanthe body of the nails, but narrower than the head. Into this slot thenails fall as they slide from the inclined upper end of the feed-slidewhen at the upperlimit of Application filed December 9, 1896. Serial N6.615,Q48. (No model.)

its movement. Such nails as do not fall into the slot, or Work their waytherein, are shaken back into the hopperin the operation of the nailer.The nails hang in arow in the slot, as shown in Fig. 6. An apron E maybe placed outside. of them to assist in keeping them in a regular row,though thisis not'indispensable. Below. this row of suspended nails isplaced a chute F, its mouth at the upper end adapted to catch the lowernail of the row as it is detached and falls. The lower end of the chuteis contracted and enters a hole in the side of the tubular stock B, sothat the nails are delivered tothe inside of said stock singly andpointdownward. The stock is provided with a suitable foot-piece G. .Thismay be flared at the bottom, as indicated by the dotted lines in Fig. 2,sot-hat the shock of the plunger in driving the nails does not tend todrive the foot into'the shingle or board and mar or split it. The foothas a contracted hole through it a little larger than the head of thenail.

A plunger H plays up and down in the stock. This has a head large enoughto give sufficient weight to the plunger as a driver. At the lower endof the plunger is a driver of hardened steel, adapted to pass to thebottom of the foot. The upper end of this driver forms a shoulder, whichon the upstroke engages a collar I, adapted to play a limited distancein the stock. It connects by a screwbwith one arm of a toggle-lever J J,the screw passing through a slot 0 in the stock. The other end of thetoggle is pivoted to the side of the hopper. To the middle of the toggleis connected a link K, coupled to a connecting-rod L, which at the otherend connects with a finger M, pivoted to a suitable bracket N, attachedto the hopper. This finger has a notch m at the inner end of it, and isadapted to catch one nail at a time and push it out of the "slot D as itis swung by the movement of the rod L. When in normal position, it actsas a stop for the row of nails. A coil-spring O, abutting against thebearing P, and a suitable shoulder on the rod holds the finger in normalposition. This shoulder may be the head of a small brush Q, which,moving back and forth over the nails at the lower end of the row, tendsto keep them free and in proper position to be caught by thereleasing-finger one by one.

A shoulder H near the upper end of the plunger engages a collar 1',which slips freely in the stock. This collar has an outwardlyprojectinglug 'i, to which is connected a rod R, the lower end of which connectswith the lower end of the feed-slide. A slot d permits the collar tomove up and down. Between the collars c and d is a coil-spring c to holdthe plunger in normal position.

A handle S, for one hand of the operator, is provided at some convenientpoint, as attached to one side of the hopper.

The operation of the device will now be understood. The operator firstlifts the plunger to the upper limit of its stroke. This carries up thecollar 0, and in so doing the notch at the inner end of the finger Mengages a nail and carries it, with the movement of the finger, out ofthe slot and drops it into the chute F, whence it slides by its owngravity to the bottom of the stock. The same movement carries up one ormore nails on the feed-slide and deposits them in position to fall intothe slot therefor. A downward thrust of the plunger drives home thenail, the downward movement of the plunger being limited by a shoulder hat the bottom of the head thereof.

As both hands of the operator are required, this nailer is intended foruse where many nails are to be driven in material already placedtherefor, as in shingling, the nailing down of rough flooring, or thelike. The operator follows up other workmen who place the material, andin this manner the nailing is done with great rapidity.

Having thus described my invention, I claim In a nailer,the combinationwith a nail-hopper and feed-slide, substantially as described, of atubular stock, a collar playing up and down therein, and connecting withthe feedslide, a collar connecting with mechanism adapted to separate asingle nail from a row thereof, a spring between said collars, and aplunger adapted to move them alternately a limited distance in thestock, as described.

I testimony whereof I affix my signature in presence of two witnesses.

JAMES XV. GRANDLE.
